Why this discourse

This discourse answers a question most meditators eventually face: which awakening factors should be developed when the mind is sluggish, and which when it is restless? The answer — investigation, energy, and rapture stimulate a sluggish mind; tranquility, immersion, and equanimity settle a restless one, while mindfulness is always useful — is one of the most frequently cited practical teachings in the entire canon on meditative troubleshooting.

Reading guide

A shared opening, a distinct challenge

This discourse's own opening explicitly refers back to “the same as the previous discourse” (SN 46.52), reusing the wanderers'-monastery frame; but the specific challenge posed here is distinct: not whether the five hindrances and seven awakening factors can be doubled, but which awakening factors suit which mental state.

Two matched fire similes, precisely calibrated

The discourse pairs two contrasting fire images with two contrasting mental states: making a SMALL fire FLARE UP (requiring dry fuel, blowing, no dirt) illustrates stimulating a sluggish mind; extinguishing a GREAT MASS of fire (requiring wet fuel, water, dirt) illustrates settling a restless one — confirmed by close reading that each simile's own physical logic maps precisely onto its own corresponding awakening factors.

A closing exception: mindfulness always useful

After carefully distinguishing which awakening factors suit which state, the discourse's own final line singles out mindfulness as exempt from this conditionality altogether — “mindfulness is always useful, I say” — confirming mindfulness's own distinct, foundational status among the seven.

Key terms

līnaṁ cittaṁ — “a sluggish mind” — the condition calling for the stimulating awakening factors of investigation, energy, and rapture
uddhataṁ cittaṁ — “a restless mind” — the condition calling for the settling awakening factors of tranquility, immersion, and equanimity
dhammavicaya... vīriya... pīti — investigation of principles, energy, and rapture — the three “wrong time to develop” for a sluggish mind... actually the RIGHT time, per the discourse's own careful reading; the WRONG time for a restless one
passaddhi... samādhi... upekkhā — tranquility, immersion, and equanimity — the three factors reversed in their own applicability compared to the stimulating set
sati sabbatthikā vadāmi — “mindfulness is always useful, I say” — the discourse's own closing exception, exempting mindfulness from the conditional logic applied to the other six factors

The text

Every genuinely translated fragment of this discourse, including both fire similes in full. Translation: Bhikkhu Sujato (CC0, SuttaCentral).

§1 — the settingThen several mendicants robed up in the morning and, taking their bowls and robes, entered Sāvatthī for alms. (The same as the previous discourse.)

§2-3 — the wanderers' own challenge“Mendicants, when wanderers of other religions say this, you should say to them: ‘Reverends, which awakening factors should not be developed when the mind is sluggish? And which awakening factors should be developed at that time? Which awakening factors should not be developed when the mind is restless? And which awakening factors should be developed at that time?’ Questioned like this, the wanderers of other religions would be stumped, and, in addition, would get frustrated. Why is that? Because they’re out of their element. I don’t see anyone in this world—with its gods, Māras, and Divinities, this population with its ascetics and brahmins, its gods and humans—who could provide a satisfying answer to these questions except for the Realized One or his disciple or someone who has heard it from them.

§4 — a sluggish mind, the wrong factorsWhen the mind is sluggish, it’s the wrong time to develop the awakening factors of tranquility, immersion, and equanimity. Why is that? Because it’s hard to stimulate a sluggish mind with these things.

§5 — the fire that won't flare upSuppose someone wanted to make a small fire flare up. If they toss wet grass, cow-dung, and timber on it, spray it with water, and scatter dirt on it, could they make it flare up?” “No, sir.”

§6-7 — a sluggish mind, the right factors“In the same way, when the mind is sluggish, it’s the wrong time to develop the awakening factors of tranquility, immersion, and equanimity. Why is that? Because it’s hard to stimulate a sluggish mind with these things. When the mind is sluggish, it’s the right time to develop the awakening factors of investigation of principles, energy, and rapture. Why is that? Because it’s easy to stimulate a sluggish mind with these things.

§8 — the fire that does flare upSuppose someone wanted to make a small fire flare up. If they toss dry grass, cow-dung, and timber on it, blow on it, and don’t scatter dirt on it, could they make it flare up?” “Yes, sir.”

§9-10 — a restless mind, the wrong factors“In the same way, when the mind is sluggish, it’s the right time to develop the awakening factors of investigation of principles, energy, and rapture. Why is that? Because it’s easy to stimulate a sluggish mind with these things. When the mind is restless, it’s the wrong time to develop the awakening factors of investigation of principles, energy, and rapture. Why is that? Because it’s hard to settle a restless mind with these things.

§11 — the mass of fire that won't go outSuppose someone wanted to extinguish a great mass of fire. If they toss dry grass, cow-dung, and timber on it, blow on it, and don’t scatter dirt on it, could they extinguish it?” “No, sir.”

§12-13 — a restless mind, the right factors“In the same way, when the mind is restless, it’s the wrong time to develop the awakening factors of investigation of principles, energy, and rapture. Why is that? Because it’s hard to settle a restless mind with these things. When the mind is restless, it’s the right time to develop the awakening factors of tranquility, immersion, and equanimity. Why is that? Because it’s easy to settle a restless mind with these things.

§14-15 — the mass of fire that does go out, and mindfulness always usefulSuppose someone wanted to extinguish a great mass of fire. If they toss wet grass, cow-dung, and timber on it, spray it with water, and scatter dirt on it, could they extinguish it?” “Yes, sir.” “In the same way, when the mind is restless, it’s the right time to develop the awakening factors of tranquility, immersion, and equanimity. Why is that? Because it’s easy to settle a restless mind with these things. But mindfulness is always useful, I say.”
